Abstract

PURPOSE:To scrupulously contract with a telephone company who operates an ISDN exchanging device in accordance with an equipment and terminal which are contained by a first-order group interface and which a subscriber has and also in accordance with traffic control expected by the subscriber. CONSTITUTION:The call classification connection number setting means 3 of the ISDN exchanging device 1 respectively and independently designates and sets the connection possible number of a voice call, a data call and a packet call which are needed by a private branch exchange 2 contained by the first- order group interfaces 1B-15B and m-n to become like n, two and two. An attribute information selection setting means 4 selects one of the three bits of attribute information among information dedicated to output connection, information dedicated to input connection and information dedicated to both directions for channel correspondence inside the first-order group interfaces 1B-15B and m-n so as to set it.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a primary group interface attribute setting method, and more particularly to a primary group interface attribute setting method in an ISDN switching apparatus.

[0002]

2. Description of the Related Art Conventionally, in this type of primary group interface attribute setting method, the attribute that voice calls (voice calls), data calls and packet calls can be connected by the number of all channels of the primary group interface is selected and set. In addition, all channels of the primary interface have unconditionally set the attribute that both outgoing and incoming connections are possible.

[0003]

In this conventional primary group interface attribute setting method, since attributes of voice call, data call and packet call are set for the interface, that is, for all channels, each subscriber is set. In some cases, it was necessary to make a contract with a telephone company that operates ISDN switching equipment in excess of the number of terminals connected to the.
For example, a subscriber has to contract for 30 channels in the A-law system and 23 channels in the μ-law system in order to enable packet connection even though only one packet terminal is connected.

Further, since all channels of the primary group interface can be connected in both directions of outgoing connection and incoming connection, if used for outgoing / incoming call of all channels, the reverse incoming / outgoing call is reversed. If the subscriber cannot expect the traffic control expected by the subscriber, and if the ISDN switching device simultaneously seizes the same channel for the incoming connection call and the subscriber for the outgoing connection call,
There was also a problem that one of the calls became an incomplete call due to channel collision.

[0005]

According to the attribute setting method of the primary group interface of the present invention, a voice call required by a subscriber accommodated by the primary group interface in the attribute setting method of the primary group interface in the ISDN switching apparatus. , A means for independently specifying and setting the connectable number of data calls and packet calls, and selecting any one of attribute information for outgoing connection, incoming connection and bidirectional connection corresponding to the channel in the primary group interface And a setting means.

[0006]

The present invention will be described below with reference to the drawings.

FIG. 1 is a diagram for explaining an embodiment of the present invention in which an ISDN switching device 1 and a private branch exchange 2 as a subscriber are connected by primary group interfaces 1B to 15B and m to n. The ISDN switching apparatus 1 includes a call-specific connection number setting means 3 for independently specifying and setting the connectable numbers of voice calls, data calls, and packet calls required by subscribers accommodated by the primary group interface, and a primary connection. Attribute information selection and setting means 4 for selecting and setting any one of attribute information for exclusive use of outgoing connection, exclusive use of incoming connection and bidirectional connection corresponding to the channel between the group interfaces. The private branch exchange 2 has voice call terminals 51 to 5n and a data call terminal 6
1, 62 and packet call terminals 71, 72 are connected.

Therefore, in this example, the subscriber and the ISDN are
Even if the maximum number of contracts with the telephone company operating the switching apparatus 1 is registered, it is only necessary to contract for n voice call simultaneous connection, 2 data calls and 2 packet calls. It is not necessary to register all n pieces as in the conventional case.

In addition, 1B-1 in the primary group interface
If the 5B channel is used as the outgoing connection-dedicated channel and the mB to nB channels are used as the incoming connection-dedicated channel, the outgoing connection call is 1B.
To 15B channels are all in use, it is possible to make incoming connections using mB to nB channels. Conversely, mB
To 1B to 1 even if all nB channels are in use
An outgoing connection call can be made using the 5B channel. here,
In the case of μ-Law, m = 16 and n = 23, and in the case of A-Law, m = 17 and n = 31.

[0010]

As described above, the present invention is based on the ISDN.
A means for specifying the number of connections of each voice call, data call, and packet call to the switching equipment as required by the subscriber, and an outgoing connection dedicated channel, an incoming connection dedicated channel, and bidirectional connection can be made corresponding to the primary interface interface channel Since the means for selecting and setting the attribute of the channel is provided, the ISDN is adapted to the equipment and terminals of the subscriber and the traffic control expected by the subscriber.
Allows detailed contracts with the telephone company that operates the switching equipment.
